Water leakage case
Baoye Building Project
Waterproof Layer Inspection for Industrial Plant at 15/F, Block A, Po Yip Building, Tsuen Wan
Project Background
In June 2021, Silver Surveyors Limited was commissioned to conduct a post-construction waterproof layer inspection for the entire floor of Unit A, 15/F, Po Yip Building in Tsuen Wan. The unit was designated as a food processing factory, and the client required verification of the waterproofing integrity to prevent future equipment damage and hygiene risks.
Technical Approach & Inspection Highlights
Comprehensive Infrared Scanning
A Fluke high-definition infrared scanner was deployed to systematically survey 18 functional zones within the plant.
Temperature differential analysis identified potential moisture retention areas.

Grid-Based Inspection Methodology
The floor was divided into 132 inspection points for precise data collection.
Compliance with Hong Kong Buildings Department’s seepage investigation guidelines.
Key Findings & Conclusion
No Hidden Moisture Detected: Infrared data showed uniform temperature distribution (＜0.3°C variation), indicating no water retention.
Waterproofing Compliance Confirmed: The construction met all regulatory standards.
Inspection Area: Dim Sum Zone Hot Kitchen Packaging Zone
Points Checked: 100 points 12 points 46 points
Result: No anomaly No anomaly No anomaly
Remarks: Stable temperature Even near heat sources Large-area consistency

Project Value
Risk Mitigation: Pre-emptive detection prevented potential production disruptions.
Legal Validity: Report signed by an RICS-certified surveyor, admissible as court evidence.
Silver Surveyors’ Insight
Industrial floor waterproofing requires scenario-specific scrutiny. This case demonstrates how systematic infrared scanning ensures both compliance and long-term operational safety.
